Description

Technical Field

[0001] This utility model relates to the field of gas detection equipment technology, and in particular to a retractable and modular gas detection rod. Background Technology

[0002] In industrial production, construction, and emergency rescue scenarios, gas leaks or accumulations of toxic gases can easily lead to safety accidents such as explosions and poisoning. Real-time and accurate gas detection is crucial to ensuring personnel safety.

[0003] The following core pain points exist in the practical application of current gas detection equipment, which constitute the research and development background of this device. Most of the telescopic gas detection rods on the market have a single telescopic structure, which has obvious shortcomings: First, the telescopic adjustment has poor reliability. Some use a snap-on fixing method, which is prone to loosening due to vibration after stretching, causing the detector head to fall. Second, the detection function is limited, and it can only detect a single type of gas. If it is necessary to detect toxic gases, combustible gases and ambient temperature at the same time, multiple devices need to be carried, which is cumbersome to operate. Utility Model Content

[0004] The main purpose of this invention is to provide a retractable and modular gas detection rod, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A retractable and modular gas detector rod includes a mounting cylinder. A limiting groove is formed on the front of the outer surface of the mounting cylinder. An arc-shaped connecting plate is fixedly connected to the rear of the outer surface of the mounting cylinder. A handle is fixedly connected to the rear of the outer surface of the arc-shaped connecting plate. A telescopic device is movably connected to the lower inner wall of the mounting cylinder. An installation device is fixedly connected to the lower end of the telescopic device.

[0006] The telescopic device includes a handwheel, a fixed rod is fixedly connected to the lower end of the handwheel, a threaded rod is fixedly connected to the fixed rod through the mounting cylinder, a threaded connecting block is threadedly connected to the outer surface of the threaded rod, a limit plate is fixedly connected to the front of the outer surface of the threaded connecting block, a lifting plate is fixedly connected to the front end of the limit plate, and a bottom block is fixedly connected to the lower end of the threaded rod.

[0007] Preferably, the lower end of the bottom block is movably connected to the lower inner wall of the mounting cylinder via a bearing.

[0008] The above solution involves a bottom block that is movably connected to the mounting cylinder via a bearing, reducing frictional resistance during the rotation of the threaded rod, making the handwheel drive smoother and preventing jamming. It also ensures the coaxiality of the threaded rod rotation and improves the operational stability of the telescopic device.

[0009] Preferably, the limiting plate and the limiting groove are connected with a clearance fit.

[0010] The above solution involves a clearance fit between the limiting plate and the limiting groove, which restricts the threaded connecting block from rotating with the threaded rod, ensuring that it only moves up and down axially, preventing the detection component from shifting and ensuring accurate detection position.

[0011] Preferably, the installation device includes connecting rods, and a plurality of connecting rods are provided. The lower ends of the plurality of connecting rods are fixedly connected to a first connecting block. The lower end of the first connecting block is engaged with a second connecting disc. The upper end of the second connecting disc has two threaded holes, and screws are threaded into both threaded holes. A detection component is fixedly connected to the lower end of the second connecting disc.

[0012] The above solution involves a clearance fit between the limiting plate and the limiting groove, which restricts the threaded connecting block from rotating with the threaded rod, ensuring that it only moves up and down axially, preventing the detection component from shifting and ensuring accurate detection position.

[0013] Preferably, the upper ends of several of the detection components are fixedly connected to the lower end of the lifting plate, and the several detection components are distributed in a circular array around the center of the first connecting block.

[0014] The above solution allows for quick assembly and disassembly of the detection components via snap-fit ​​and screw fixing, facilitating the replacement of different sensors. The connecting rod and connecting block work together to ensure stable installation of the detection components, making it suitable for detection in multiple scenarios.

[0015] Preferably, both screws pass through the first connecting block and are threaded into the two threaded holes.

[0016] The above scheme utilizes a circular array of detection components, which can simultaneously collect gas and temperature data from different angles, improving detection coverage and data accuracy. Furthermore, the components are fixed to the lifting plate, ensuring synchronous movement during lifting and lowering, thus ensuring stability and reliability.

[0017] Preferably, the detection component includes a housing, a temperature sensor and a gas sensor are fixedly installed on the front and rear sides of the upper inner wall of the housing, a plurality of support rods are fixedly connected to the upper inner wall of the housing, a lighting lamp is fixedly connected to the lower ends of the plurality of support rods, an air inlet is provided at the lower end of the housing, and the upper end of the housing is fixedly connected to the lower end of the second connecting plate.

[0018] The above solution integrates dual sensors and a light source in the detection component, enabling simultaneous detection of gas and temperature without the need for additional lighting in dim environments; the air intake ensures gas flow, resulting in more accurate detection data and more comprehensive functionality.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, a threaded transmission telescopic structure composed of a handwheel, a fixed rod, a threaded rod, and a threaded connecting block is adopted. Compared with the snap-on fixing, rotating the handwheel drives the threaded rod to rotate, so that the threaded connecting block can be stably raised and lowered along the threaded rod. With the clearance fit between the limiting plate and the limiting groove, it can accurately position and effectively prevent loosening caused by vibration. In complex environments, such as when there is machine vibration in chemical production workshops or slight ground vibration in mines, the probe can also be kept in the set position to avoid falling, ensuring that the detection work can be carried out continuously and stably, and providing reliable data support for safe production.

[0020] 2. In this utility model, the detection component integrates a temperature sensor and a gas sensor, which can simultaneously detect ambient temperature as well as toxic and combustible gases. When conducting detection operations, staff do not need to carry multiple devices to detect different parameters separately, making the operation more convenient and efficient. Taking the detection of petrochemical storage tank areas as an example, it can acquire multiple key data at once, reducing detection time, improving work efficiency, reducing the risk of omissions caused by frequent equipment switching, and comprehensively improving the accuracy and convenience of gas detection.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1-4 This utility model provides a technical solution: A telescopic combined gas detector rod includes a mounting cylinder 1. A limiting groove 2 is formed on the front of the outer surface of the mounting cylinder 1. An arc-shaped connecting plate 3 is fixedly connected to the rear of the outer surface of the mounting cylinder 1. A handle 4 is fixedly connected to the rear of the outer surface of the arc-shaped connecting plate 3. A telescopic device 5 is movably connected to the lower inner wall of the mounting cylinder 1. An installation device 6 is fixedly connected to the lower end of the telescopic device 5.

[0027] In this embodiment, the telescopic device 5 includes a handwheel 51, a fixed rod 52 is fixedly connected to the lower end of the handwheel 51, a threaded rod 53 is fixedly connected to the fixed rod 52 through the mounting cylinder 1, a threaded connecting block 54 is threadedly connected to the outer surface of the threaded rod 53, a limiting plate 55 is fixedly connected to the front of the outer surface of the threaded connecting block 54, a lifting plate 56 is fixedly connected to the front end of the limiting plate 55, and a bottom block 57 is fixedly connected to the lower end of the threaded rod 53; the lower end of the bottom block 57 is movably connected to the lower inner wall of the mounting cylinder 1 through a bearing; the limiting plate 55 is clearance-fitted with the limiting groove 2.

[0028] Through the above scheme: when the telescopic device 5 is working, the handwheel 51 is turned, which drives the fixed rod 52 to rotate, thereby causing the threaded rod 53 that passes through the mounting cylinder 1 to rotate synchronously. When the threaded rod 53 rotates, the threaded connecting block 54 on the outer surface cannot rotate with the threaded rod due to the clearance fit between the limiting plate 55 and the limiting groove 2. It moves up and down along the threaded rod axis. The threaded connecting block 54 drives the limiting plate 55 to rise and fall synchronously, thereby causing the lifting plate 56 at the front end of the limiting plate to move up and down, realizing the height adjustment of the mounting device 6 and the detection component 66 to meet the requirements of different detection positions.

[0029] In this embodiment, the installation device 6 includes connecting rods 61, and several connecting rods 61 are provided. The lower ends of the several connecting rods 61 are fixedly connected to a first connecting block 62. The lower end of the first connecting block 62 is engaged with a second connecting plate 63. The upper end of the second connecting plate 63 has two threaded holes 64, and each threaded hole 64 is threaded with a screw 65. The lower end of the second connecting plate 63 is fixedly connected to a detection component 66. The upper ends of the several detection components 66 are all fixedly connected to the lower end of the lifting plate 56, and the several detection components 66 are connected to the first connecting block 62. The detector is arranged in a central ring array; two screws 65 pass through the first connecting block 62 and are threadedly connected to two threaded holes 64; the detection component 66 includes a housing 661, on the front and rear sides of the upper inner wall of the housing 661 respectively, a temperature sensor 662 and a gas sensor 663 are fixedly installed, a number of support rods 664 are fixedly connected to the upper inner wall of the housing 661, and a lighting lamp 665 is fixedly connected to the lower end of the number of support rods 664. An air inlet 666 is opened at the lower end of the housing 661, and the upper end of the housing 661 is fixedly connected to the lower end of the second connecting plate 63.

[0030] Through the above scheme: In the installation device 6, several connecting rods 61 connect the lifting plate 56 and the first connecting block 62. After the first connecting block 62 is engaged with the second connecting plate 63, screws 65 pass through the first connecting block 62 and the threaded hole 64 and are tightened to achieve a stable installation of the detection component 66. The detection component 66 is distributed in a ring array. The air inlet 666 at the lower end of the outer shell 661 allows gas to enter. The temperature sensor 662 and the gas sensor 663 detect environmental parameters synchronously. The excellent lighting lamp 665 fixed by the support rod 664 can assist detection in dim environments and ensure accurate data acquisition.

[0031] It should be noted that this utility model is a telescopic combined gas detection rod. During use, first, hold the handle 4 and check whether the telescopic device 5 inside the mounting cylinder 1 is flexible. Fix the second connecting plate 63 to the first connecting block 62 with screws 65 to ensure that the detection component 66 is installed firmly. Select the corresponding sensor according to the detection requirements. Turn the handwheel 51 to drive the fixed rod 52 and threaded rod 53 to rotate. The bottom block 57 reduces frictional wear through the bearing. The threaded connecting block 54 is limited by the limiting plate 55 and the limiting groove 2, and rises and falls along the threaded rod, so that the lifting plate 5 6. The installation device 6 and the detection component 66 are driven to the target height. The air inlet 666 of the detection component 66 draws in gas, and the temperature sensor 662 and the gas sensor 663 detect it simultaneously. In a dim environment, the excellent lighting 665 is turned on, and the ring array of detection components 66 collects data from multiple angles to ensure comprehensive detection. The handwheel 51 is turned in the opposite direction to retract the detection component 66 to the initial position. The screw 65 is unscrewed to separate the first connecting block 62 from the second connecting plate 63. The detection component 66 can be replaced or repaired. After cleaning the air inlet 666, it is stored.
